Recent Advances in Asymmetric Wettability Dressings for Wound Exudate Management.

The management of wound exudate is of vital importance for wound healing. Exudate accumulation around wound prolongs inflammation and hinders healing. Although traditional dressings can absorb wound exudate, they are unable to drain exudate in time, often resulting in a poor feature with wound healing.

A novel pigeon paramyxovirus type 1 isolated from a sick racing pigeon in the Qinghai-Tibet Plateau of China shows high virulence in chickens.

Highly sensitive temperature sensors based on the fluorescence intensity ratio of dual-emissive lead-free metal halides.

Given that optical thermometers are widely used due to their unique advantages, this study aims to address critical challenges in existing technologies, such as insufficient sensitivity, limited temperature measurement ranges, and poor signal recognition capabilities. Herein, we develop a thermometer based on the fluorescence intensity ratio (FIR) of Sb-doped CsNaInCl (CsNaInCl:Sb). As the temperature increases from 203 to 323 K, the thermally induced transition from triplet to singlet self-trapped excitons (STEs) leads to enhanced 455 nm photoluminescence (PL) from singlet STE recombination.

formed CuSn alloy from multivariate metal-organic frameworks for tunable CO electroreduction.

A molecular ligand separation method based on multivariate metal-organic frameworks (MOF) is developed to precisely regulate CuSn alloy for tuning the selectivity of HCOOH and CO in CO reduction. With this method, the agglomeration and heterogeneous nucleations of metals are effectively inhibited during the electrochemical transformation of CuSn-MOFs into highly pure CuSn alloy. The low Sn content favors CO production, while the high Sn concentration facilitates HCOOH formation.

Synthesis of a three-phase heterojunction NdVO/VO/BiVO by cation exchange method for the degradation of anionic azo dye orange II.

Embracing Nature's Wisdom: Liposome-Mediated Amplification of Electrochemiluminescence for the Sensitive and Selective Immunoassay of Serum Amyloid A.

Serum amyloid A (SAA) is a key biomarker for diagnosing inflammatory responses in diseases like influenza and COVID-19. An electrochemiluminescence (ECL) biosensor has been constructed for signal enhancement in SAA detection by encapsulating 4,4',4″,4‴-(1,3,6,8-pyrenetetrayl) tetrakis-benzoic acid (TBAPy) into liposomes. Such biomimetic encapsulation shields the biologically important membrane to avoid aggregation of TBAPy and prevents quenching.

Simultaneous Detection of Hydrogen Sulfide and Peroxynitrite Dysregulation with a Sequentially Activated Fluorescent Probe in Ulcerative Colitis Disease.

Ulcerative colitis (UC), often referred to as "green cancer", is a chronic inflammatory bowel disease with an unclear etiology, closely associated with the imbalance of hydrogen sulfide (HS) and peroxynitrite (ONOO). HS exhibits anti-inflammatory effects at physiological levels, but excessive concentrations can compromise the intestinal barrier, while ONOO aggravates inflammation. To facilitate the molecular-level monitoring of these compounds in UC, we developed a novel fluorescent probe, , capable of simultaneously detecting HS and ONOO via distinct fluorescent channels in a cascade mode.

However, the precise molecular steps that regulate RANKL signaling remain largely unknown.

Revealing the decision-making practices in automated external defibrillator deployment: insights from Shanghai, China.

In recent years, the government has promoted the increased deployment of automated external defibrillators (AEDs) in public places with dense crowds, which is of great significance for ensuring that residents enjoy equal health rights. However, it is still unclear what factors decision-makers take into account when formulating deployment plans and whether these factors are related to local characteristics such as population distribution and socioeconomic conditions. Taking Shanghai, China as the research area, we adopted the kernel density estimation and spatial autocorrelation analysis to explore the spatial distribution characteristics of AEDs.
